T0 ALL WHOM IT MAY GONCERN:

Be it known that I; A. MERRITT ASAYot` the city and county ofPhiladelphia, and State of Pennsylvania, have invented a new and usefulImprovement in Cards for Artificial Teeth 'y' and I do hereby declarethat the following is a full and exact description thereof, referencebeinghad to the accompanying drawings, and to the letters of referencemarked thereon. i I

The nature of my invention consists in constructing cards or slips forholding'one or more sets of articial teeth, in the manner adopted, bymanufacturers, with the wax coating only on'one side. `'.Ihe usual modeis to coat both sides of the cards or slips to which the teeth areattached, and when the name or trade-mark of the manufacturer appears,to stamp it in one side of the slip, v To do this 'requires aconsiderable quantity of wax, and is otherwise objectionable, especiallywhen the cards, by'transperta-tion or otherwise, are subjected to anincreased temperature 6i' the air, in which case they are liable tostick to the boxes or cases which hold them. To obviate thesedifficulties, Icoat hut Vone side of the card with the adhesive coating,and when the manufactnrers name or trade-mark appears on the cards, Iprint it ou the face thereof before coating the other side with wax.

`The construction of the cards or slips, and process ot" forming them,`will be understood by the following description. i

The accompanying drawing, which makes a part of this specification, isan isometrical view of the slip for holding the teeth, on an enlargedscale.

A- is a strip of paper, on which the manufacturers card is printed. B isa slip of thick blottingpaper, on which itis pasted. C is a coating orlayer ofvwax on the reverse. side of the piece B, covering its wholesurface. On this coating one'or more sets of teeth are stuck, in theusual manner adopted by manufacturers.

My process of constructing the cards or slips is as follows: I print themanufacturers name or trade-mark on sheets of paper in the usual mannerof printing labels. Any kind of paper will answer the purpose, yet Iprefer it being thick, with Vthe side glazed which is printed on, toavoid the ,wax striking through it from the blottin'gpapei-in coatingthe latter as hereinafter described. The printed sheets I paste onsheets of thick blotting-paper, und then connect the combined sheetstogether in pairs, with the printed sides facing each other. I then sealtheir edges, to prevent the coatingwax running between the sheets., bypasting strips of paper over them. Ifthe printed sheets are large enoughthey may be doubled, in which case only three ot' their edges requiresealing. The next process is coating theouter surfaces oi' theblotting-paper with wax. This I do by dipping the pieces in melted wax,repeating t-he dipping in'the .method ofdipping candles, until therequisite thickness of 7the coating is obtained. Whenthc sheets are coldI cut off their sealed edges to separate them, and cut them intoseparate cards, as representedin the drawing.

'Ihe coating may be cheapened by adulterating the wax with one or mercingredients that will not destroy its cohesive and adhesive properties,or some equivalent may be usedfin place of wax. Instead of making thecards of two pieces, as described, the print-ing may be made directly onthe blotting-paper, which should in this case have an increasedthickness, and should be v'arnished or glazed on Ythc printed side, soas to prevent the wax striking through it.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The cards or slips for holding' artificial teeth, with the wax onlyon one side, substantially as above described. Y v

2. Printing tne manufacturer-s name or trade-mark on one side o f theslip, and coating the opposite side of the same with beeswax, or anequivalent material, substantially as described and for the purposesspecified..

3. 'Ihe process ot' preparing the sheets out of which the cards or slipsarc formed, to receive the coating of wax on' their outer surfaces,substantially as described.

i In testimony that the above is my invention, I have hereunto set myhand and affixed my seal, this tenth day of May, A. D. 1867.
